Toward an ultra-broadband emission source based on the Bismuth and Erbium co-doped optical fiber and a single 830nm laser diode pump

Abstract

We demonstrate a broadband optical emission from Bi/Er co-doped fiber and a single 830nm laser diode pump. The ultra-broadband mechanism is studied and discussed in details based on a combination of experimental measurements, including luminescence, differential luminescence and ESA, on fiber samples of different Bi and Er concentrations. The Er co-doping in Bi doped fiber is found to be effective for broadband emission, by enhancing not only luminescence at C and L bands but also that at O and shorter wavelength bands. The luminescence intensity between 1100 and 1570nm is over -45dBm/5nm in single mode fiber using a few meters of Bi/Er co-doped fiber and offers a modest ~40dB dynamic range and a broad bandwidth of ~470nm for an OSA based spectral measurement.

An Erbium-Doped Fiber Source with Near-Gaussian-Shaped Spectrum Based on Double-Stage Energy Matching and LPFGs

“…Therefore, many researchers have carried out in-depth research and proposed abundant design schemes for realizing Erbium-doped fiber sources with a high performance. The spectral bandwidth of Erbium-doped fiber sources has been broadened by inserting a LPFG [7,8], adopting a two-stage configuration [9], employing a nonlinear optical loop mirror [10], using a piece of Bi/Er co-doped fiber [11] or by means of a mode-locked Erbium-doped fiber laser [12]. Some works have also been reported on Lband [13,14] or C+L band [15] Erbium-doped fiber sources for the immediate expansion of the fiber-optic communication window.…”

Wideband bismuth- and erbium-codoped optical fiber amplifier for C + L + U-telecommunication band

“…There have been many efforts to achieve optical amplification using glasses and fibers codoped with Bi and Er having broadband near IR luminescence [8][9][10][11][12][13][14]. Unfortunately, by now, net gain covering wide spectral range has not been demonstrated in these materials.…”

Photoluminescence properties of Bi/Al-codoped silica optical fiber based on atomic layer deposition method

“…Since then the bismuth-doped materials have been studied widely. The broadband luminescence of Bidoped glasses [4,5] and optical fibers [6,7] in the near-IR region covers from 1.1 m to 1.8 m, while these spectral region's fiber lasers and broadband sources are very promising for a number of important applications. In 2005, the first bismuth-doped fiber was fabricated by the modified chemical vapor deposition (MCVD) method [8].…”
